A high-resistance connection (HRC) is a hazard that results from loose or poor connections in traditional electrical accessories and switchgear which can cause heat to develop, capable of starting a fire. [1] Glowing connections occur when relatively high current exists in a relatively large resistance object. Heat comes from power dissipation ...
Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Aluminum provides a better conductivity-to-weight ratio than copper, and therefore is also used for wiring power grids , including overhead power transmission lines and local power distribution lines , as well ...
Switch reliability is largely a question of the contact force: a force that is reliably adequate, but never excessive, encourages long life. Common applications of micro switches include the door interlock on a microwave oven , leveling and safety switches in elevators , vending machines , arcade buttons, and to detect paper jams or other ...
